This question describes 4 carbon atoms that form a square... this seems to be the only problem described like this. Will we have to know how to draw these and problems like 43?

I believe that if a problem is drawn a certain way (square or chain), they will tell us as they did in 47 and 43. If we haven't learned that, or we are not expected to know it, then they usually tell us what information we need to complete the problem.

Also drawing this molecule in a line would result in formal charges not equal to zero so the only way to draw it while minimizing the formal charges on the atoms would to draw it as a square

Hydrocarbons often form structures like this, with carbon as the central atom and hydrogens branching off- for example benzene rings. So just predict such structures for molecules with multiple carbons and hydrogens.
